There is a balance as well I think. Security is critical, but there is no way to ever guarantee that 100% no matter how much transparency you try to have. People who are willing to break the law will always find ways to get away with it. Should the whole world adopt radical transparency because some people are criminals? Are all crimes equal?
I do see a point behind taking a stance to favor certain designs but I do not think unlimited transparency is a good idea. I think people who are not thieves, not breaking the law, not deliberately damaging the community, do not always benefit from for instance having the amount of money they are earning or holding known to the entire world. As we know, this can make people even bigger targets and nothing the blockchain can do can protect people , so the transparency done wrong actually makes it much worse.
Some privacy in my opinion is critical for improving security. The privacy on the level of amounts people hold and amounts sent or received, should be private between the parties, or as transparent as they like, as in they should be able to select which accounts can see how much money they have or their transactions rather than have everyone see everything like in Steemit.
